Why Would You Need an Ultrasound?

Generally, ultrasound is common for a person who is pregnant but that is not the only use of this equipment.

Ultrasound is a non-invasive procedure that detects changes in the appearance of organs, tissues and blood vessels. It is considered to be safer than an X-ray since it does not expose the patient to any radiation. It can also provide clearer pictures than an X-ray and the imaging is in real-time.

Normally, a radiologist is tasked to look after an ultrasound scan. However, some physicians are well equipped to proceed with the method, for instance, an Obstetrician.

They use a transducer to detect the sound waves as well as the echoes. The area where the probe will be placed is treated with a gel to make sure that the sound waves can be clearly detected as they travel through the skin.

Now, why would you need an ultrasound? Here are the reasons.


As mentioned above, a private ultrasound scan in London is often used for people who are pregnant.  It can either be a pelvic ultrasound, where the transducer is set on a patient’s abdomen or transvaginal ultrasound, in which a probe is inserted into the vagina. It is also used in diagnosing possible growth of tumours in the ovary, fallopian tubes or uterus.



In cardiology, ultrasound is referred to as echocardiography since it is used to assess the heart and its valves. It is also used to assess the motion of the heart’s wall along with the quantity of blood pumped by the heart during a stroke. It can be done in 2 different methods, trans-thoracic and trans-oesophageal. Trans-oesophageal provides clearer images of the heart than trans-thoracic, though the first one may be more invasive.

The echocardiography can give detailed pictures of the heart chamber making it easier for doctors to asses if there is any blood clot in it. It can also detect if there is any abnormal fluid build-up in the pericardium.

Blood vessels

An ultrasound can detect blood clots within the vein and artery blockage. It is often used for patients who have had a stroke to determine if there is enough oxygen flow in the brain. An aneurysm can also be detected by an ultrasound, especially those that are abdominal in nature.

Abdominal structure

An ultrasound is the first thing that doctor’s use to determine if there are any gallstones or possible infection within the gallbladder, appendicitis and even kidney stones.

Other uses

Other uses may include imaging for nodules, growth andtumours in the thyroid gland and knees.

Ultrasound is not only for the diagnosis of a disease but rather it is also used to screen for disease and help in its treatment. The quality of the image produced by an ultrasound is dependent on several factors such as obesity, the presence of gas, and accuracy of the regulator.

If your doctor requests that you undergo an ultrasound, you should not be worried about it. They are just trying to eliminate several possible conditions to ensure that they are able to provide you with the care that is appropriate for you.
